10 Claims.

Our invention relates to peg boards which are employed to facilitate accounting methods. Such a board is described in United States Letters Patent of Robert L. Connor and Nelson S. Welk, issued March 15, 1934, No. 1,958,743, and more particularly our invention is an improvement on a device which is described in a copending application, Serial No. 10,131, filed March 9, 1935, by Donald A. Nevin and Nelson S. Welk.

In that application a peg board is described which consists of an inclined board adapted to receive a plurality of sheets of paper. The peg board is provided with a paper support termed a peg bar from which the sheets of paper are suspended, the sheets being arranged in shingled relation. These sheets contain data which is. to be totalled by the aid of a line guide which extends across the entire board.

A cross bar is arranged to support the paper holding peg bars. The cross bar is suspended by flexible belts, one end of each of which is attached to a pulley mounted upon a shaft at the rear of the inclined board. This pulley, when rotated by mechanism provided for that purpose,

* raises the sheets of paper and retains them in parallel arrangement.

As described in that application the paper is lowered by gravity acting on the weight of the metal peg bars. We have found in practice that When'the device is incorrectly operated or without the peg bar being attached, the cross bar does not possess sufficient weight for gravity to overcome the frictional resistance produced by contact against the surface of the supporting board.

This sometimes causes the belts to buckle and come off of the pulleys. Inasmuch as these pulleys are located inside of the machine it renders the machine temporarily inoperative until the container is opened up and the belts again placed upon the pulleys.

Practice has also shown that it is possible to purposely or carelessly put the machine out of commission by holding the cross piece immovable or by throwing it back over the top of the inclined board and then operating the lowering mechanism.

Our invention has for its principal object to provide means for positively lowering the cross bar and metal peg bars supported thereby.

A further object of our invention is to make it impossible to throw the cross bar back over the top of the inclined board.

As described in the said application, a micrometer screw adjusting device is provided to permit the operator after spacing from one line to an other to move the papers slightly upwardly or downwardly and thus to compensate for any variation in the spaces between the lines which may result from inaccuracy in ruling the lines or may be brought about by a shrinkage of the paper.

We have also found in practice that it is frequently desirable to back space the paper a distance of one or two spaces. To do this by the use of the micrometer screw adjusting device described in said application prevents rapid operation and entails the loss of a considerable amount of time.

We have also found in practice that it is desirable in some conditions, when the device has been set for double spacing, to single space at certain points in the operation of the device. When the device is operated by means of the micrometer adjusting device, or by changing the space control knob from double to single space position and back action or by depressing the operating lever half way, a great deal of time is consumed.

A further object of this invention is to provide an improved adjusting means which will not only permit close adjustment of the sheets of paper either upwardly or downwardly but will also permit rapid movement for a distance of three spaces or any part thereof in either direction as may be desired by the operator.

Our means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which- Fig. 1 is a perspective view taken from the front of the machine;

Fig. 2 is a perspective view taken from the rear of the machine;

Fig. 3 is a. detail sectional View of an idler pulley and its supporting means, taken on line 3-3 of Fig. 2;

Fig. 4 is a fragmentary detail view of the belt adjusting mechanism;

Fig. 5 is a fragmentary detail view taken on the line 5--5 in Fig. 4 in the direction indicated by the arrows.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the peg board l is provided with a cross bar 2 to the ends of which are secured bolts 5 and 1. These belts are wound upon pulleys 5 and 6. The belts 3 and l pass over idler pulleys l and 8 mounted at the top of the peg board I on the shaft 9 mounted in suitable bearings. The pulleys and 6 are mounted upon a shaft ID, the rotation of which operates to wind up the belts 3 and 4 thus shifting the position of the cross bar 2.

Inasmuch as the operating mechanism for this device is described in application Serial No. 10,131, we shall not describe that part of the structure as the present invention does not pertain to it.

As shown in Fig. 2 of the drawings, we nrount athird pulley 2| upon the operating shaft ID to which we attach one end of a belt 23. This belt 23 is wound on the pulley 2| in an opposite direction from that with the belts 3 and 4 wound on the pulleys 5 and 6. The belt 23 is passed through a slot 24 provided at the center of the bottom edge of the peg board I. An idler pulley 25, which is provided with flanges at each end, prevents the belt 23 from contacting the edges of the slot 24. The idler pulley 25 rotates on a shaft 26 which is supported at either end by bearing brackets 27 clearly seen in Fig. 3. The brackets 21 may be permanently secured to the board in any suitable or desired manner such as spot welding or by screws.

On the face of the peg board I we form a sunken channel 24" which is adapted to receive belt 23 so as to permit the upper surface thereof to be below the surface of the board I and. thus avoid any interference with the sheets of paper (not shown) which may be resting or moving on the board.

The opposite end of the belt 23, to that which is attached to the pulley 2 I, is fastened at the center of said bar, to the bottom of the cross bar 2 by a rivet or eyelet 29 or any other suitable or convenient manner. The length of the belt is such that it will effectually prevent the cross bar 2 from being thrown back over the top of the board I.

It will be apparent to persons skilled in the art that the rotation of the shaft I!) in a direction opposite to that employed in elevating the cross bar 2 will wind the belt 23 on the pulley 2| thus operating to draw the cross bar 2 downwardly on the surface of the board this motion being permitted by the unwinding of the belts 3 and 4 from the pulleys 5 and 6 since they are also attached to the shaft 0. It will be apparent from the foregoing that in this manner we provide a positive means for drawing the cross bar 2 downwardly instead of relying upon gravity for that purpose.

Our means for tightening and loosening the belts used for raising and lowering the paper (which is entirely independent of the ratchet wheel line spacing mechanism described and claimed in patent application, Serial No. 10,131) comprises a belt tightening and loosening rod 30 which is supported at both ends by an arm 3| which is rigidly attached to a rod 32. Means for adjusting the tension of the rod 30 on the belts comprises a link 33 which is rigidly attached to the end of the bar 32. A suitable handle or knob 34 being provided for convenience of operation. The knob 34 is provided with a stem 34' which passes through a hole in the arm 33 to which it is permanently attached by welding or in any other suitable or desired manner. The end of the stem 34 is chisel shaped and is adapted to frictionally engage the teeth of a gear segment 35. In practice we employ spring steel for the construction of the link 33 and the resilience of this metal furnishes sufficient spring tension to hold the point of the stem 34' in engagement with the teeth cut on a segment 35. The said segment 35 may be conveniently secured to the end wall of the casing by screws 36 or in any other suitable or convenient manner.

As described in the said application, pressure upon an operating handle 3'! will rotate the pulleys 5 and 6 and wind the belts 3 and 4 thereon, thus raising the cross bar 2 and the sheets of paper (not shown), one or two spaces for each movement of said handle 31 depending upon the position of the space control knob 38.

The shaft l0, carrying the pulleys 5, l and 2| which are fixedly mounted thereon, is rotated by means of a crank 4| which is provided with a handle 40 for convenient rotation as fully described in said application Serial No. 10,131. By rotating the pulleys in one direction the cross bar 2 will be drawn upwardly, this being permitted by the unwinding of the belt 23 from the belt 2|. By turning the crank 4| in the opposite direction the plates will be unwound from pulleys 5 and 6 and the belts 23 will be wound upon the pulley 2| thus drawing the cross bar 2 downwardly. Should it occur that the lines on the sheets of paper do not coincide with the line finder (not shown) a slight forward movement of knob 34 from one tooth to another of the said segment 35 will tighten the belts 3 and 4 due to their passing under the frame rod l6. This moves the arms 3| in an arc and will swing the rod 30 about the center of the shaft 32 and will, as a consequence raise the sheets of paper.

Obviously a reverse movement will cause the belt to loosen and permit the cross bar 2 and the peg bar and attached paper (not shown) to lower the mechanism. Adjustment of the knob 34 on the said segment 35 will tighten or loosen the belts 3 and 4 sufiiciently to move the paper approximately three spaces. The center belt 23 is provided with sufiicient slack to permit of this adjustment.

It has been found in practice that the amount of this adjustment may be increased or decreased merely by changing the length of the arms 3|. It has also been found in practice that in operation and at the top line of the paper the adjusting knob 34 should be set approximately at a central position on the said segment 35 as clearly seen in Fig. 4 so as to afford approximately an equal adjustment in either direction.
